mei_controller sounds good to me.

The bus is not physical neither. It's really items that we add to this bus,
watchdog could be the next candidate for example.

I still believe it makes sense to use mei_device for what we add to the MEI
bus. I'd be fine with mei_bus_device as well, but that would somehow look
a bit awkward. Greg, Arnd, any preference ?

as only the technology specific parts of the MEI driver (e.g. nfc.c) will use
that mei_device structure.
